Boston Bruins forward Shawn Thornton was suspended for 15 games without pay the NHL on Saturday for punching and injuring unsuspecting Pittsburgh defenseman Brooks Orpik.

Thornton went after Orpik during a stoppage in play Dec. 7, slew-footing him to the ice and punching him twice. Orpik sustained a concussion and was taken off the ice on a stretcher. Earlier, Orpik hit Boston's Loui Eriksson, knocking him out of the game with a concussion.

Thornton was assessed a match penalty.

Orpik hasn't played since the game.

The suspension will cost Thornton $84,615. He served three games of the ban before the length of the suspension was determined.
